    More question:

    We knew that clapboard of airintake separates boundry-layer from fuselage for drag decrease, which means it’s better to area extended more. But why the area of inboard clapboard of MiG-31’s air-intake is less than outboard and its lip be cut as radin shape.

    Impressive!
    If it was a bird-view or up-view, it would be better……

    According to fighter-planes
    MiG-31M MTOW is 52000kg
    deduct internal fuel 16350kg and dropped fuel tank on outboard pylon 2500L×2 (approx 4000kg) plus max weapon load 6 R-37 weights 3600kg,
    remaining 28050kg for inboard pylons and dry weight for airframe.
    If we assume the dry weight is 23000kg then only 3000L external fuel tank which has been used by Su-24 for each inboard pylon can reach the weight remained.
    Is this illation reasonable?

    That speed problem solved by what?

    Are there anyone who can give a confirmation that H-6K will reach 3500km combat radius with 15t weapon load here?
    My friend told me this information by an unprofessional news.

    …or may not…

    Yes, I don’t get it. Would you mind translate those Russian to English? What did he say?

    12 years ago, there was pretty scandalous and famous statement of that time’s RuAF commander Mikhalov.

    Ergo, there is no testing data for max. speed relaesed……..? Say nothing of degressive speed!

    the T-50’s max speed is limited by airframe materials and structures. The head of the VVS consciously chose to reduce max speed from the initial requirement of Mach 2.35 down to Mach 2.15 and then to Mach 2 so avoid having to strength certain aircraft parts and thus adding weight to handle those dash speeds, which aren’t very important in the first place.

    May I require the source of the degressive speed for PAK-FA?

    Российский истребитель пятого поколения Т-50 (ПАК ФА) в ходе испытаний установил рекорд скороподъемности, сообщил ресурс AirForce – Swords Of Sky.

    Самолет набирал высоту со скоростью 384 метра в секунду. С такой быстротой он оказался бы на вершине Эвереста за 23 секунды, отметил портал.

    Т-50 проходит программу госиспытаний – в том числе с оружием. По словам главкома ВВС России Виктора Бондарева в 2016 году будет построен последний, 11 самолет испытательной партии. Авиазавод в Комсомольске-на-Амуре готов к серийному производству ПАК ФА. Интерес к российскому самолету проявили многие государства. На 2020 год запланировано начало сборки экспортной версии Т-50.

    Летно-технические характеристики истребителя засекречены, однако известно, что он соответствует требованиям, предъявляемым к самолетам пятого поколения. То есть достигает сверхзвуковой скорости без использования форсажа, обладает сверхманевренностью (за счет двигателей с управляемым вектором тяги), малозаметен для радаров и универсален в боевом применении. В обшивку ПАК Фа интегрированы антенны радаров и аппаратура радиоэлектронной борьбы. Первые дают пилоту круговой обзор, вторые скрывают Т-50 от локаторов и вражеских ракет.

    Who can translate this to English perfectly.

    Does the LERX of the J-20 201× still work as vortex generator or merely works for the ugly tumor under it.

    An unstable jetfighter for J-20 is suspicious even.

    I have no idea why the window which looks like boundary layer spill duct on X-35 later disappeared from F-35

    It seems that DSI of the j20-11 would be different from F-35.

    Lothar:
    According to the video from youtube, what you told me was right. However, that bottum engine distance the inlet lip more closer than the top engine, so clearly, the buttom one get airflow first, how could the top one steal the airflow in sharing air pipeline even while the buttom one during maximum power.
